Peripheral blood (May-Grünwald-Giemsa stain) of a patient with hairy cell leukaemia. A typical hairy cell (->) can easily be distinguished from a normal lymphocyte (lower right).

Hairy cell from a hairy cell leukaemia. Typical are the monocytic type nuclei with loose chromatin, and the grey-blue, heterogeneous cytoplasm. The hairy protrusions may be missing in some cases.

This 'hairy' lymphocyte comes from a person suffering from an active infection (without any malignant disease). The granula identify it as a T or an NK cell.

Reticulocyte staining. Characteristic HbH cell in a case of α-thalassaemia. Today, blood films are no longer investigated for HbH cells. Instead,
α-thalassaemias are diagnosed by molecular genetic tests.
